The Claas brothers

Under the name “Gebrüder Claas” (Claas Brothers), the firm became well known all around the world. So who were the company’s founding fathers, August, Bernhard, Franz and Theo, and what were they like?

Rear mowers for the most discerning of customers.

Faultless reliability.

DISCO CONTOUR.

The CLAAS range of DISCO CONTOUR rear mowers provides suitable machines for all farms and agricultural businesses. This efficient all-rounder combines the outstanding performance of the MAX CUT mower bar with other DISCO benefits. Central hitching ensures perfect ground-contour following in all models. The 120° road transport position also makes the machine compact and safe on the road.

Optimum ground-contour following.

The mower units in the CONTOUR model series are hitched at the centre of gravity, so they can pivot freely and adapt to the ground contours. The correct adjustment height is indicated with arrow markings on the booms.

Solid construction.

The construction of our machines is robust and clearly laid out, with mower components built for maximum strength and stamina. To protect the hydraulic components, they are integrated in the frame structure wherever possible.

All DISCO rear mowers have mechanical breakback protection. The attachment is inclined at an angle of 15°, so that in the event of a collision with an object the mower is lifted up and back. Mowing can then continue after a brief reset operation.

The 120° transport position and centre of gravity location close to the tractor provide outstanding stability, for safety and ease of handling on the road. There is also a mechanical lock system to hold the mower securely when in the transport position.

A practical support frame option is also available, with or without rollers, so that the machine can be parked away in the compact transport position when the job is finished. The support trestle on rollers is ideal wherever space is at a premium, allowing the mower to be moved easily without the aid of a tractor.

For the Groiner Milch KG dairy partnership in Niederrhein, North Rhine-Westfalia, as for any other dairy farming business, feed quality is a key sucess factor. They have a herd of 500 dairy cows to feed, on a farm with some "very uneven terrain with ditches all over the place," says Felix Streuff, one of the partners. Whenever the conditions permit, he likes to mow with the reduced PTO speed (850 rpm).

He is extremely pleased with the contour following and cut quality from his mowing combination of a DISCO 3200 FC PROFIL and DISCO 3600 C CONTOUR. He has no doubt that this improves the quality of the feed, which in turn significantly boosted the farm's milk production last year.

High area coverage with reduced power requirement.

Side-mounted rear mowers.

In the same way as the large-scale mowers, CLAAS side-mounted rear mowers also feature professional-level technology. MAX CUT is available as from a working width of 2.60 metres.

Continuous suspension.

Powerful coil springs provide the mower suspension, transferring a proportion of the machine’s weight to the tractor. The arrangement of the springs ensures that the residual weight is distributed evenly across the full length of the mower bar. Adjustment of the ground pressure according to harvesting conditions is carried out without the use of special tools.

The pivot point is located well inside, so the mower in road transport position is hardly any wider than the tractor. Having the centre of gravity close to the tractor ensures excellent stability on the road, and the mower is automatically secured mechanically in the transport position.

Adjustable mounting bolts are used to set the tractor track width. This allows use of the full working width and setting of the optimum overlap when operating in combination with a front mower. Pins at different heights ensure easy and convenient hitching.

Mechanical breakback protection, consisting of robust pawls and elastomers, effectively prevents damage to the mower bar. Once the overload device is activated, the operator simply has to lower the mower and briefly back up.

Rear mowers with inline mower bar

CLAAS inline bar.

The inline mower bar is extremely robust, thanks to its high-quality steel housing. Generously dimensioned gear wheels plus sturdy ball bearings ensure a long service life and high functional reliability. The notch recess on the bottom of the bar allows dirt to exit at the rear. The bar is also brushed clean by the stubble left standing.

Weight relief.

The mower bar is suspended on two coil springs, one for each half of the bar. The springs interact to maintain a steady ground pressure across the entire cutting width. This results in constant mower suspension and optimal ground-contour tracking, even in difficult operating conditions. The benefits include lower frictional resistance, protection of the grass cover, and a clean and consistent cut.

With just one control lever, the mowing unit can be raised at the headlands or swung into the transport position without having to use the three-point hydraulic linkage or modify basic settings. The mowing unit is lowered to the ground evenly over its full width via the horizontal parallel lifting function. The ground pressure when mowing remains even, and the cut clean.

The overload protection responds immediately upon collision with an obstacle. To continue driving, the tractor needs only to be briefly backed up, after which mowing can resume. The mower bar is thus protected at all times.

The mowing unit can be folded up for transport via a single-acting ram. A mechanical lock is also provided to secure the unit in place during transport. This ensures that the unit is held firmly in place. The pivot point is located well inside the machine for a minimum transport width.

The lower link pins of the mowing unit are fully adjustable, to adapt the mower to the track width of the tractor, enabling you to fully exploit the chop width at all times. The open, inverted U-frame mounting also provides maximum freedom of movement for the drive shaft.

The DISCO 210 RC has two rollers engaging with each other in a "V" configuration, with a spring for protection against impacts with extraneous objects. The pre-set tension and roller interval can be set according to the harvesting conditions. The swathing plates are adjustable without the use of tools for tidy crop deposition.
